An 18-year-old Hispanic man residing in Los Angeles, California, presented with bilateral masses at the base of his neck, which he had for 2 months. The left-sided mass had been spontaneously draining straw-colored fluid for 5 days. Three months prior to presentation, he had received a diagnosis of pneumonia; his condition improved after a course of azithromycin. He denied ever having a fever, weight loss, contact with any sick persons, or sexual activity; using illicit drugs; or traveling outside of southern California.
